Title: Verification system
IPC: G06Q40/00
Filed: 1973-07-23
Abstract: 1439163 Selective signalling MOSLER SAFE CO 23 July 1973 [28 July 1972] 35037/73 Heading G4H Magnetic or embossed data on a credit card 10 is read in reader 13 and supplied to recirculating shift register 25 to be stored as sixteen binary coded decimal digits. The register is coupled to matrix switch 27 (Fig. 3, not shown) which contains five sets of switches A-E each switch set having four outputs representing binary 8, 4, 2, 1 and each output being selectively connectable to sixteen inputs coupled to the respective binary level of the sixteen digits C1- C16 in the register. The switches are arrange so that the outputs form five b.c.d. numbers composed of bits from randomly selected states of the register 25. Each switch set feeds a number limiter arranged to suppress the 4 and 2 level bits if an 8 level bit is present to restrict the number formed to the range 0-9. The five digits so formed are added in adder 30 and fed to an X/Y switch initially feeding the sum digit to Y register 38. The contents of register 25 are circulated three digits and a new number is obtained and fed to X register 39. The process is repeated until the X and Y registers each hold a four digit word. The digits of each X, Y address word are used in pairs to access truth tables or memories 22 and to successively produce digits T<SP>1</SP> 1 -T 4 <SP>1</SP> which are then stored in register 17. The credit card owner enters a memorized number M 1 <SP>1</SP>-M 4 <SP>1</SP> in register 16 which is compared with the number in register 17 to see if a predetermined condition is met. Digits from a counter 32 may be fed to the adder if all digits on the credit card are the same.

Abstract: 1,071,956. Stripping bobbins. MACHINEFABRIEK M. BROUWER & CO. N.V. Aug. 27, 1964 [Aug. 30, 1963], No. 35164/64. Heading D1F. In a hydraulically- or pneumatically-operated machine for stripping yarn waste from bobbins, movement of a pedal 28 operates a valve whereby a piston rod 15 is advanced to rotate a ring 14 so that slots 13 coact with pins 12 to advance jaws 8 carried by pressure members 9 into gripping engagement with a bobbin 18 below a spent winding 19. When the pressure on the exhaust side of piston 16 has fallen to a predetermined value, the pressure in a control member, Fig. 3 (not shown) is relieved so that the resultant movement of a membrane therein operates another valve whereby a piston rod 6 is advanced and a plunger 7 depresses the bobbin, the yarn 19 being cleared therefrom by the jaws 8. The pedal is released to restore the machine in preparation for the next bobbin. If an operator's hand is trapped beneath the descending plunger 7, a spring-loaded ring 20 is depressed thereby so that a cam 26 actuates a valve 27 which applies pressure to the membrane thereby reversing the second valve and retracting the rod 6.

Abstract: 1278963 Converting ATES COMPONENTI ELETTRONICI SpA 15 July 1969 [1 Aug 1968] 35492/69 Heading H2F A power supply unit for a television receiver comprises a rectifier D1 connected to the supply mains Vr, the output of the rectifier being smoothed by C 1 and fed to a stabilizer comprising transistor Q1 and a zener diode D2, the stabilized current being supplied to a shunt capacitor C5, the voltage being adjusted by a chopping transistor Q2. The chopped voltage may be smoothed by the primary of the line deflection transformer Tr and capacitor C7 so as to provide a voltage Va for the rest of the television receiver. The collector of Q2 is connected to a tapping on the primary of Tr so as to provide an increased D.C. voltage for the line output transistor Q3. The chopper control pulses may be derived from the transformer Tr whilst the bias for Q1 is derived by rectifying at D3 the flyback pulses across windings n2. This arrangement thus provides short circuit protection. A starting circuit C1 provides initial charge on C7 from the output of rectifiier Dl. In Fig. 2 (not shown), a single transistor is used to provide both chopping and current stabilization. The voltage Va may be adjusted by alteration of taps on transformer Tr. The use of a stabilized supply allows corresponding variation of E.H.T. voltage and deflection amplitude hence the raster size remains constant.

Abstract: 1,254,809. Hydraulic transmissions. GENERAL MOTORS CORP. 23 July, 1970 [10 Nov., 1969], No. 35715/70. Heading F2D. An hydraulic transmission utilizing an hydromechanical or purely hydrostatic arrangement to provide a number of drive ranges including a Low forward and Low reverse, includes an hydrostatic transmission comprising a pump 59 and motor 65, the pump being controlled by a servo control 42 in response to upshift and downshift signals 100, 110 from a ratio governor 108 responsive to accelerator pedal position and engine speed, and a Low valve 10 being effective to utilize the downshift signal 110 when the engine is idling and the transmission is in Low range, forward or reverse, to establish a predetermined ratio in the transmission. The predetermined ratio may be just sufficient to counteract the creep inherent in the transmission to establish a real neutral, or may be sufficiently high to overcome the creep and establish a ratio in forward or reverse depending on whether the transmission is in forward or reverse Low range. As shown, the servo control 42 is adjusted by a servo actuator 58 to opposite ends of which the upshift and downshift signals are directed from the ratio governor 108 via shuttle valves 50, 54, a forward/reverse valve 64 and a Low spool valve 112 which, in all ratio ranges other than Low, connects the downshift signal 110 to the forward/reverse valve. In Low range, the valve 112 is spring-biased to its shown position connecting the downshift signal 110 to the Low valve 10 which comprises a sleeve 12 urged to the right by a spring 32 and to the left by a plug 44 acted on by reverse pressure 48 when the transmission operates in reverse. Removable shims 35, 28 on the sleeve allow adjustment of the valve of the predetermined ratio established in Low, which may be different for forward and reverse. With the sleeve 12 in one of its end positions, and the engine idling, a downshift signal in line 20 from valve 112 is directed to one of lines 52, 56 and via shuttle valves 50, 54 to the servo actuator 58, consequent movement of the servo control 42 causing a spool 16 in the valve 10 to follow up to progressively cut-off the restrictions 24<SP>1</SP> or 26<SP>1</SP> in the sleeve 12 to the lines 52, 56.

Abstract: 784,792. Printing machines. TIMSON, E. A. Dec. 6, 1955 [Dec. 10, 1954], No. 35816/54. Class 100(2) In inking mechanism comprising an inking drum supplied by a back-and-forth moving ductor from an intermittently and slowly driven fountain roller mounted in an ink trough, the fountain roller is driven by a back-and-forth moving member 8 having a part 19 arranged to contact the periphery of a rotatable edge cam 20 of progressively varying radius adapted to limit the movement of the said member and associated with a rotary dial registering against a fixed index or markings: As shown a continuously driven pinion 16 drives a gear 15' attached to a cam 11 free on an extension 1a of the fountain roller shaft; the follower roller 10 on the arm 8 pivoted at 17 is biased towards the cam by a spring 14, the arm 8 being linked at 9 to a pawl lever 7, also free on the shaft 1a; a pin 6 on the lever 7 carries two sideby-side pawls 4, 5, the tips of which are spaced apart by half a tooth 3a of a ratchet wheel 3 fixed to the shaft 1a; thus rotation of the cam 11 causes oscillation of the levers 8, 7 and intermittent rotation of the ratchet wheel 3 and fountain roller. A second arm 18 fixed to the arm 8 carries the pin 19 which contacts the snail cam 20 integral with a circular dial (Figs. 1 and 2, not shown) carrying projections for manual rotation; the setting of the cam 20 thus determines the extent of the clockwise (non-operative) movement of the pawls 4, 5. A spring-pressed ball engages depressions in the back of the dial to hold it in the position set, which is indicated by markings (corresponding to the depressions) on its face and a fixed index on a casing enclosing the pawl-and-ratchet mechanism. The dial may alternatively carry a single pointer registrable against a circular series of markings on the casing, and the ratchet mechanism may be of the toothless kind (roller in notch).
